I guess when it comes right down to it; my story is not much different than most married guys. I have a good looking wife who is much less interested in sex than I am. If I initiate sex, she will usually do it just to avoid an argument. But most of the time, she can take it or leave it when it comes to sex. At least that is what I used to think until the last few months when I discovered her "darker" side.

Over the years, I've learned that she wants and enjoys sex the most when she is ovulating. During those few days when she is fertile, her subconscious must be telling her to breed so she gets horny and really likes it when I fuck her hard and cum inside of her. The rest of the month, I'm lucky to get a hand job from her. She is my second wife and during my first marriage, I had a vasectomy. I'm her first husband and she has never had kids so although her body is telling her to breed and procreate, it will never happen with us. Before we got married, we talked about the fact that she could never have kids if she married me and she said she was cool with it and didn't want them anyway. But deep down inside, I think she longs for a baby every now and then.

So I've learned to make the best of those few "golden days" each month. It is during those times when we have the best sex and when she is game for a little experimentation. I've learned that when she gets horny and is ready to breed, she likes her sex a little rough with some light BSDM. She especially likes to be tied up and fucked while I talk dirty to her, calling her a slut and a cock hungry whore. It always gets her hot.

Recently, I started to build on my own deep dark fantasies during these hot encounters. After I tie her up spread eagle, I blindfold her and tell her that I'm bringing in a group of guys to help me with the fucking. She says, "god no" and I say, "too bad bitch, you are all tied up and there is nothing you can do about it". Then I fuck her with her various dildos and vibrators while telling her that each of them is a different cock. As I "gang fuck" her with the dildos, I always know when she is getting ready to cum because she starts to moan and say, "please don't fuck me with your bare cocks, please don't cum inside of me and make me pregnant". Whenever I hear those words, I know it is my sign to stop the dildo fucking and give her my real cock. As soon as I stick it in her tight pussy, she says, "no, no, don't fuck me with that bare cock, you will make me pregnant," and I just keep fucking her harder and harder until I feel the walls of her pussy start to contract and I let go and fill her with my cum. That puts her over the edge and she screams "oh god, I told you not to cum in me, don't knock me up!" as she shakes the bed with her orgasm and her pussy contracts like a milking machine on my cock squeezing out every last drop of my cum. I guess her conscious mind is telling her to not get pregnant but her inner, subconscious mind is screaming to breed and she just can't help having an orgasm every time she gets filled with cum, even though my cum contains no sperm.

Afterwards, I untie her and we cuddle. On a good night, I'll get it up again and we just have straight sex after that without the bondage, toys or fantasies. Usually, we will get in a 69 where she enjoys sucking my cum covered cock while I eat out her cum filled pussy until we both cum in each others mouths.

Recently, my fantasies have become more and more adventuresome. After I tie her up and blindfold her I tell her that I brought in a room full of black studs with big cocks and I'm going to watch while they gang bang her. She says, "god no, they will make me pregnant with their big, thick loads of sperm filled cum and I'll have a black baby"! But as always at the end of the fantasy, she gets off as I cum inside of her. I even bought a big thick, 10" black totally realistic vibrating cock to fuck her with. I pretend that it is my cock and I hold the base of it against my pelvis, right above my cock. Then while I have her tied up spread eagle, I "mount her" in the missionary position and rock my hips back and forth while fucking her with the big black vibrator. It gets me so hot to see it slicked up with her pussy juice as I ram it in and out of her pussy. And as always, almost on cue, when she gets close to having an orgasm, she pleads for me to not cum in her and knock her up. At that point, I replace the black vibe with my cock and after a few strokes, we both cum together.

I have got to admit that the bolder I get in the fantasies, the more I'm beginning to actually want to act out the fantasies for real. I have suggested it to her and she immediately says "hell no bud, fantasy is all you will ever get out of this one!" To be honest, I don't understand my obsessions with wanting to watch her get fucked. When we first met, I was jealous of her lipstick and I would get green with envy, thinking of the guys she had fucked before me. We used to fight about that all of the time. And yet as we get older, I want the very thing that used to make me crazy with jealousy years ago.

That brings me to the part where the line was crossed between fantasy and reality....a line that my wife will never cross back over.

It all happened quite accidentally. It was totally unplanned. We had to go out of town for a Saturday business meeting and we decided to make a long, three day weekend out of the event. I had made a mental note before we left that she would probably be ovulating that weekend so I packed a few of her dildos and some rope just in case. She must have had the same thoughts because as I found out later, she did some packing of her own in anticipation of some serious breeding.

My business meeting was over by noon and then we had the rest of the weekend to ourselves. We took a walk in a nearby park and held hands and stole an occasional kiss. Later, I took her to a nice restaurant with a view of the city lights. After her second glass of wine, I could sense that I was accurate about the timing of her ovulation....she was definitely getting that "fuck me" look in her eyes. So I paid the bill and we went back to the room.

When we got back to the room, for some reason, I just felt that something was out of place. I looked in the bath, the closet, in the dresser and everything was fine. Then it hit me. Our room was one of those that had a set of doors between our room and the adjoining room. Each room had a door with a latch and so both doors would have to be unlatched from within their respective rooms, for anyone to get from one room to the other. I went over and checked the door and discovered that the latch on our side was in the unlatched position. So if the people on the other side wanted to, they could unlatch their door and get right in our room. The locking mechanism was jammed and I couldn't get it to lock. However the second door that went to the other room appeared to be locked. So I called maintenance and they said they would send someone up right away to fix it.

In the mean time, my wife unpacked her special "provisions" for our sex filled weekend. She got undressed and put on her sexiest outfit: a white lace corset with white thigh high stockings held up by garters. Then she put on a black leather mini skirt that barely covered her bare ass and pussy. She topped her "fuck me" outfit with a new pair of bright red 6" heels. She looked like a high priced, Vegas call girl. She said that she would hide in the bathroom when the maintenance guy got there, which in itself, started to make me hot and fantasize. While we were waiting for him to show up, she lay back on the bed, leaned back on the pillow against the headboard and crossed her legs. I suddenly had this incredible urge to find a bunch of big black studs to help me breed her. She was too fucking hot to keep to myself. Little did I know that I would soon get my chance to see her get fucked by a monster black cock.

After waiting a while for the maintenance guy to show up, I turned on the TV and started to check out the movie selection. I went to the adult menu and there was a movie called "slut housewife tries black cock". Without thinking, I punched in the movie selection number and in a few minutes, we were watching a horny housewife getting seduced by her husband's black friend.

The story was about a white housewife whose husband wanted her to fuck his black buddy but she absolutely refused. He finally gave up and then one night, the guy came over to drink beer and shoot pool with them. During the course of the evening, one thing let to another and eventually they started to play "strip" pool. The woman was down to her g string and she had huge cream colored tits with big dark aureoles and nipples. The next shot, the black guy missed and took off his boxers to reveal a massive thick, jet black 10" cock with big veins bulging and a flared mushroom head. You could tell that the woman was getting hot, but she still wasn't ready to fuck the black stud and fulfill her husband's fantasy.

So the black guys suggested that just him and her play the next game and if he won, she would succumb to her husband's fantasies and let him fuck her. If she won, he would go home.

The woman was a pretty good pool shooter and it came down to the last ball. She called the 8 ball in the side pocket and as she leaned over the table to set up for her shot, her big tits practically touched the felt. She hit the ball strongly and the 8 ball slammed into the pocket but the cue spun off to the left and scratched in the corner pocket.

The woman conceded that she had lost and went over to the black dude. He proceeded to go down on her and eventually, she started to get into it all and ended up taking his cock in every hole while her husband watched and joined in any way he could.

I could tell by wife's breathing that she was starting to get aroused so I started to fondle her stocking covered legs. As I watched the movie, I now more than ever wanted my wife to take on a black cock and I was beginning to think that she was finally coming around. As I ran my hand up her thigh, she leaned back and as she did, her nipples popped out of the corset. I immediately took one in my mouth as my fingers reached her shaved pussy lips. She was already soaking wet and so for the moment, I forgot all about the maintenance man and I told her to wait a moment. I took a pillow case off of a pillow and used it to blind-fold her. Then I got the rope out of my suitcase and tied her in her favorite submissive position, spread-eagle on her back.

I stood back and admired my prim and proper conservative wife, dressed like a whore in the corset, the stockings, garter and the black leather mini skirt with the red heels. It was more than I could stand and I ripped my own clothes off and started to go down on her sweet pussy. I nibbled on her clitty and ran my tongue in and out of her wet lips. When I stuck a finger in her pussy, she started a rocking motion and I knew she was ready for some heavy duty fucking.

So I got out the 10" black vibe and started to fuck her slowly. I remember thinking at the time that I have never seen her so into fucking the black cock and so I told her, "do you want more of the black cock?" and she said "yes, god yes, it feels so good". The movie must have gotten to her also. So I gave her more and more, deeper and deeper and she kept taking all of it. I was looking forward to plunging my own cock in her and filling her with my spermless cum when I heard a knock on the door. "Shit, it's the maintenance guy" I said. She said, "what if he comes in and sees me like this"? Although the thought of seeing the look on his face while seeing my slut wife lying spread eagle with a big black vibrator in her pussy was hot, I knew she would never go for it.

So I told her that I would go and tell him to come back later. I got up but I left the black vibrator stuffed in her pussy to the hilt and left it on the high speed so she wouldn't lose her momentum. She was rocking and moaning about how good the black cock felt inside of her as I walked away, almost delirious with pleasure and pretty much unaware of whether or not I was even there.

I went to the door and opened it a crack, but the guy was gone. He had left a stiff paper door hanger note on the door knob and when I grabbed the note, I dropped it and it went sailing across the hall. Like an idiot, I stepped out to get it and when I did, the door slammed shut behind me.

I almost freaked...here I was in the hallway of a hotel, without a stitch of clothing on, sporting my best wood and my naked wife was tied up inside to the bedposts in her hottest fuck me outfit. I knew that even if she could hear me calling for her, she could not get up to let me in. And I'd be damned if I was going down to the lobby desk naked.

Then I remembered that the door in our room between the next room was unlatched. I made a quick decision and went to the room next door and knocked. The door opened in a few seconds and as it did, I covered my bare and now very soft cock with both hands. To my surprise, a well built black dude opened the door and when he saw me he said "what the fuck!"

He almost slammed the door in my face but I stopped him, showed him the door hanger and told him what happened, although I didn't tell him that my wife was tied up in the next room with a black vibrator up her pussy.

He agreed to let me in my room through the inner door. As he walked across the room, I couldn't help but admire his body. You could tell he worked out because he was all muscle. He had obviously just got out of the shower and all he had on was a white towel wrapped around his waist. He looked like some kind of stud getting ready to walk on the set of a porn movie. For a moment, I thought again of acting on my fantasy of watching my wife fuck a black stud, but then I knew she would never go through with it.

He unlatched his door and opened ours and as he did, he couldn't help but see my wife lying there on the bed, looking like a slut with the black cock vibe in her pussy, vibrating away. She was really rocking her hips as if she were getting the fuck of her life. Both of us stopped cold, not knowing what to say. And then as if on cue, my wife started to moan "oh god, fuck me with that big black cock, give it to me please, harder, deeper, I love your black meat, fuck me like a white trash whore, give it to me now, I got to have your black cock....please, please fuck me with your black cock now!"

He looked at me and I looked at him and we didn't have to say a word. I knew what he wanted to do and he knew that I wanted him to do it.

Quietly, we walked across the room and he got on the bed on his knees above her and took off the towel. I was shocked. His cock looked exactly like the vibe! It was thick and 10" long with big veins on a shaft that was topped off with a huge, flared mushroom shaped head. For a moment, I was jealous but then I felt my own cock getting hard again and I knew it was now or never.

I said to my wife, "sorry I was gone but I'm back...so you like the black cock"? She said "yes, I love it, I need it, I crave black meat but I need you to fuck me with it!" I said, OK baby and I reached down and pulled out the vibe with one hand and turned it off. I nodded to the black dude and without skipping a beat, he plunged his cock in her pussy.

My wife started to gasp and said, "oh my god, it feels so real, so good, so fucking good, oh god honey, fuck me with that big black cock!" I said, "yes honey, it feels real cause I got a new black cock for you to fuck". She said, "oh god, thanks, this is the best black cock you have ever got me....so real, so good, god I can't get enough of it....fuck me harder and deeper with that black meat!"

At that moment, I realized that everything they say about well-hung black studs is true. This guy was amazing and for a moment, I felt sorry for my wife. He was pounding her like a jack hammer and I could hear his big, plum sized black balls slapping against her ass with every down stroke. But my wife was taking him to the hilt on every stroke and rocking with him. I could tell that she was having the fuck of her life.

Finally, she started to say, "oh god, don't cum inside of me, don't make me pregnant with your black baby seed"! I knew that she was about to cum and for a moment, I almost told him to stop but I knew that it would ruin her orgasm and his and deep down inside, I wanted him to unload his sperm in her fertile womb. So I just let him fuck away and as she started to cum, I knew her pussy muscles would be contracting and starting the cum milking action that I have come to enjoy so much. He couldn't help himself and as he started to erupt in her, he yelled out, "oh god you have such a tight pussy....that's it baby, milk the sperm out of me". For a second, my wife froze up but it was too late for her to stop. Her subconscious had already taken over and was doing everything it could to take on his sperm and get her pregnant. She went over the edge anyway and started to scream out "oh god, no, please don't cum in me and make me pregnant with your black baby seed....please", and then she went into a huge orgasm. I could tell by the look on his face that her pussy was contracting and milking all of his sperm into its fertile womb. She rocked and moaned like I have never seen her before.

Our new friend continued to pump her, pushing his seed deeper and deeper in her womb. As he did, I could hear a sloshing sound as some of his massive load, started to ooze out around her very tight opening. I looked down and saw that his black cock looked like it had been covered with vanilla frosting. About this time, my wife said, "take off the fucking blindfold". When I did, she looked down at muscular body and his mammoth cock and she said, "untie me".

As soon as I did, she got up and looked at his massive cock which was starting to get soft, and she looked at me and said, "I hope you like what you saw bud, because you have finally turned me into a black cock slut." "From this day forward at this time every month, you are going to have to find me enough black cock and sperm to satisfy my fertile womb. But first things first, I need more of this black monster in me." She reached over started to suck and lick his cum and her pussy juice off of his thick cock like it was a chocolate ice cream cone with whipped cream topping. When she had him cleaned up, she told him to roll over on his back. He was rock hard again and his cock looked more like 12" now instead of the 10" before.

She lifted her leg over him and slid down on his pole. I got behind her so could see her take him in. Her pussy opening seemed so tight and small compared to his massive pole. He was so huge, it almost seemed like she was getting fisted.

I watched her slowly lower herself and heard her moan as his thick, mushroom shaped head popped in. At that point, her tight pussy lips were wrapped around his cock head almost like a thick rubber band and it looked like it wouldn't come out that easily. She must have sensed that also and so she started a gentle rocking motion. I could tell that she was using this motion to rub his cock head against her clitty and it was having an effect on her pleasure button.

She leaned forward and fed him one of her perfect tits and he sucked hungrily on her hard nipple while he fondled both of her tits. She looked back over her shoulder at me and said "here it goes bud, watch me take all of his hot black meat in my womb." With that, she leaned back and slowly lowered herself down his shaft, inch by inch. On the way down, she moaned with every inch and said, "oh god, I've never been filled and stretched by a cock like this before....I'm such a slut for big black cock...I just got to have more!"

Finally, she bottomed out and for a few minutes, she stayed down and gently rocked on his pole as if she were trying to get him even harder and bigger. I've never seen her so into a cock but then again, I've never seen her fuck a 10" black cock either.

Then she slowly lifted her ass and slowly made her way back up the pole. By this time, my face was about a foot away from her ass and I could hear a sucking sound, as her pussy grudgingly gave up its prize as she slid up, higher and higher until she got to where his flared cock head was once again locked into her by her tight pussy lips. He reached around her and grabbed her creamy white ass cheeks with his big black hands and pulled her back down. As soon as she bottomed out, he lifted her up again, ready for the next plunge. By this time, his shaft was well coated with her pussy juice and the remnants of his first load of cum. He continued to move her up and down on his cock until she told him that she wanted to take him doggie, while she and I got in a 69.

At this point, I was more than shocked. Here was my conservative, sexually repressed wife acting like a total wanton slut. I had been stroking my cock while I watched her fuck this stud but I still hadn't cum so I was up for anything she wanted at this point.

So I got on my back and she got above me. She took my cock in her mouth and it felt so good to finally get some of her loving for myself. In a minute, our black stud friend got behind her and I had a bird's eye view once again of him entering her now swollen pussy lips. At first, he had trouble getting the head to go in and so she reached down and grabbed his shaft and guided it in. He started slow and got the flared head to spread her lips enough to allow another invasion of his massive pole. Once he got the head in, he started to rock in short, gentle strokes until she got used to the size again. But in a minute, he was buried in her to the hilt and picking up speed.

Soon, he was pounding her again with long hard strokes and his balls were slapping up against her clitty with every stroke. I moved my head up and tongued her clitty and eventually, I was also tonguing his shaft. It was my first bi adventure and I loved it.

All the while, my wife was giving me an amazing sucking. After about ten minutes of taking his cock in and out from behind, I could tell she was getting ready to cum. But this time, her words were very different. She started to moan "come on you bastard, cum inside me, fill me with your sperm, knock up my fertile pussy"!

That was all it took for him and he began to grunt as he shot another huge load of cum in her womb. As her pussy muscles began to contract and start the cum milking action, I could hear her pussy making a slurping, sucking sound, drawing every last drop of his sperm into her womb. All of this was too much for me and I began to shoot my own load into her waiting mouth. She sucked every drop of my cum and kept sucking and licking my shaft.

As soon as our new fuck buddy started to soften up, he pulled his cock out of her tight hole and immediately, his cum and her pussy juice began to ooze out of her swollen lips into my waiting mouth. It was my turn to eat cum and I was surprised at how good it tasted.

For the rest of the weekend, my wife fucked our buddy, taking him in every hole multiple times. He even invited some of his buddies over and they also fucked every hole and filled her fertile womb with their sperm. I'll save the details of her encounters with his buddies for another story.

And by the way, the maintenance guy came back and this time when I opened the door, I was surprised to see that he also was a black stud. I let him in but he never got around to fixing the latch. I'll save that story for later also.

I'd like to say that ever since that weekend, our sex life has taken on new dimensions, but unfortunately, it hasn't happened. On the days of the month when she is not ovulating, it is pretty much sex, or non sex as usual. But when "that time" of the month comes around, she is a slut for black cock and she can't get enough of it. I spend the rest of the month arranging the encounters but recently, she puts on "fuck me" outfits and goes to bars and picks up the black studs on her own.

This has been going on now for almost a year and she is not pregnant. Like I said before, I am her first husband and I have had a vasectomy. She was always on birth control before we met and so she has never had the opportunity to get pregnant. I'm convinced at this point that she really can't conceive for whatever reason. She doesn't seem to care and neither do I. All I know is that she has this insatiable urge every month when she is ovulating, to get her pussy filled with black cock sperm and I'm enjoying the black cock slut side of my wife.
